The $20 Billion Question: What Are Investors Buying at the Boring Company?

The Boring Company is raising $4 billion at a $20 billion valuation. It brought in about $2.7 million in revenue last year.

That's a revenue multiple of roughly 7,400. If you find yourself arrested by the arithmetic, you're looking at the wrong question.

The competitor headline frames this as a story about Elon Musk's empire growing. That's the surface read — as if the point is to count the number of companies he owns, the way you'd count the number of projects a contractor bids on. The more interesting question is what kind of investor writes a check for $20 billion to a company whose operational footprint is a shuttle service beneath the Las Vegas Convention Center. What are they actually buying?

I suspect they aren't buying tunnels.

Here's the record. The Boring Company was founded in 2016, spun out of SpaceX in 2018, and has raised $908 million across three rounds since. Its last priced round was April 2022, when it closed $675 million from Vy Capital, Sequoia, and Founders Fund at a $5.675 billion valuation. So this new $20 billion number is a 3.5x jump in four years.

In that same period, the company operates 11 stations in Las Vegas, has moved over 4 million passengers, and employs 707 people. The Vegas Loop's actual peak throughput is around 4,500 passengers per hour. The company claims its final form will serve 90,000 per hour. A public policy professor at UNLV, Ben Leffel, puts the system's current scale closer to buses or high-frequency shuttles than to mass transit. That's not a dismissal of the concept — it's a description of where it actually is.

Beyond Las Vegas, the track record is thin. The company has pitched tunnels in Washington, Baltimore, Chicago, Los Angeles, San Jose, San Antonio, Miami, and Australia. Most of these fell apart. In San Antonio, the company ghosted the regional mobility authority in 2022, failing to respond to agreements or follow-up calls. In Nashville, where it's building its "Music City Loop," construction crews walked off the site in November 2025 over unpaid wages and safety concerns. The subcontractor had been on the job 123 days and had received roughly 5% of what was owed. Nevada regulators found nearly 800 environmental violations at the Vegas site. Industry observers say the company's tunnel-boring machines are neither innovative nor cost-effective compared to established standards.

So if the operational picture looks more like a series of half-finished pilots than a scaling infrastructure business, where does $20 billion come from?

The answer is what private-market investors have started calling the "Elon premium." It's the willingness to pay above-market valuations for access to Musk's orbit. The logic isn't hard to trace. Early investors in Twitter made money when the platform folded into xAI. SpaceX went public at $1.75 trillion and despite falling roughly 50% from its offering peak, it's still one of the most valuable companies on earth. The premium isn't irrational — it's a bet that proximity to Musk's ecosystem compounds. You're not funding a tunnel company. You're buying a seat in the room where the next thing gets decided.

But there's a difference between a premium and a hallucination. A premium implies that the underlying asset eventually earns its way up. A hallucination is when the valuation is so far ahead of the fundamentals that no plausible ramp closes the gap.

Let's try a thought experiment. The Vegas Loop is approved for 68 miles of tunnel and 104 stations. The first 2.1 miles cost around $47 million to build. Even if every mile costs the same and every station brings in convention-center-scale ridership, you'd need a revenue model that generates roughly $294 million per year just to hit a 67x multiple — the kind of number a high-growth software company commands, not a capital-intensive transit operator. The Las Vegas Convention and Visitors Authority recently committed $25 million over five years just to maintain the original convention-center loop. That's a subsidy, not a business model.

The Dubai project — 4 miles in phase one at $154 million, expanding to 14 miles at $545 million — is more ambition than proof. Nobody has said who's paying for it.

So the central contradiction is this: the $20 billion valuation requires investors to believe the Boring Company is something it demonstrably isn't yet. Not a mass-transit operator. Not a profitable infrastructure business. Maybe not even a functional tunneling contractor at industry standards. What they're believing in is the meta-bet — that Musk's ability to assemble resources, attract talent, and shape narratives is itself the asset. That the tunnels are secondary to the gravitational field.

I'm not sure that's wrong. It depends on what you think Musk's gravitational field is worth. But it does mean the valuation tells you nothing about whether the Boring Company is a good tunnel company. It tells you everything about whether you believe in the premium.

The thing about premiums is that they work until they don't. Tesla's stock fell 15% recently, erasing $215 billion, after the company missed earnings and showed negative cash flow. SpaceX shares have dropped about 50% from their IPO peak. The premium absorbed both hits, but absorption is not immunity.

The test is simple. If you strip away Musk's name, his X megaphone, and the option value of being inside his ecosystem, is there a business worth $20 billion? If the answer is no — and the evidence suggests it is — then the valuation is a bet on the founder, not the company. Founders age, lose focus, or make mistakes. Ecosystems fragment. Premiums compress.

The way to think about this isn't to ask whether the Boring Company will eventually justify its price. It's to ask whether you're comfortable buying tunnels or buying access to Elon Musk. Those are different investments. One has cash flows. The other has reputation risk.

If the deal closes at $20 billion, the smart move is to look at the investor list. The people writing that check know exactly what they're buying. The question for everyone else is whether they want to be in the same room.
